Brown Rot Blossom Blight and Fruit Rot

Brown rot causes blossom blight in spring and fruit rot at harvest on stone fruits. You see blighted flowers and brown, decaying fruit. The disease favors warm, wet conditions. Prune out infected blossoms, maintain good orchard sanitation, and apply fungicides during vulnerable flowering periods.

These must be supplemented by chemical methods especially in the wettest areas such as west of the Cascade Range. Remove and destroy infected twigs and branches in summer.
